If you are a system administrator, and you frequently work with the UNIX Shell Terminal Command, you've probably have come to a point where you want to know in which directory you are currently working. So to display the directory you are at, execute the following command:

Code/Command:
pwd


Once you have entered this command, the shell will display the directory you are in

example:
Code/Command:
/home/username


think it stands for: Print Working Directory (I guess)
